Hex Colors

Hello again, for those of you out there having problems understanding why every color has a value in the computer here is a mish-mashed explanation I’ve written up:

Hex Colors-

When you select a color in the computer you are given a hex value with six numbers or letters it should look something like this:

#000000

When you break up this hex color you end up understanding that of the six numbers there are only 3 pairs of values that correspond to colors.

#    00        00        00
Red        Green        Blue         otherwise known as RGB, the                             color space that is used for screens

The values are working with are a range of 16 however, since you have to take this range of 16 and compress it into a single digit number you end up with a new numbering system that looks like this

0,1,2,3,4,5,6,7,8, 9,  A,  B,  C, D,  E,  F

Now what do these numbers and values actually do for you well you should recognize these very general hex colors

#000000            #FFFFFF
Pure black            pure white

Now it should all be pretty understandable as you are working with the color wheel now.

So #FF0000 is a pure red as it had the maximum amount of red value, (the first two digits of the hex number) and no amount of green or blue, making it a pure red. (two values each of 16 for the red)

What is the reason for the 16 values? Well… There are 256 color values, every value set of two digits has the capacity to be a double value of 16, the square root of 256 is 16. So there are 256 possible shades of red, 256 possible shades of green, and 256 possible shades of blue. However when you look at the color mixer in these programs you will see that the highest value you will get is 255, being the highest value with the 256th value is 0, an absolute black.

For example when mixing colors you can do something like this:

#3A0000 and you will end up with a darker red
#880088 you will end up with a midtone violet

Make sense? Its just math and mixing.
